A botnet has emerged that tries to steal personal financial information while pretending to sell iPhones.

The botnet, an army of PCs infected and controlled by a Trojan program called Aifone.A, has infected about 7,500 computers, according to PandaLabs, the threat-analysis division of Panda Software.

When the user of an infected PC goes to Apple's official iPhone web page to purchase the product, the malware instead displays a phony page designed to look like the authentic one. Any information entered in the phony page is captured by the botnet controller.

PandaLabs says this botnet is sophisticated enough to divert search results for the iPhone to the phony site, and can even display pop-ups and banners to send users to the spoofed website.
